I frequently play around with multivariate techniques like K-means cluster analysis in SPSS. There were some big holes in the SPSS procedure that performs cluster analysis so wrote an SPSS Macro to automate what I wanted to be done. Below is a quick demo of the macro in use. It can really save a bunch of time! A few things mine does differently is:
- assigns labels to the segments (these will be changed later but butter than just a 1,2,3)
- Computes frequencies on the size of the segments (Why SPSS doesn’t do this automatically is beyond me)
- Color-codes and merges the significance testing in with the profile-plot showing what is different.
